"Isocoma arguta" is a species of flowering plant in the daisy family known by the common name Carquinez goldenbush. It is endemic to Solano County, California, where it grows in the Sacramento-San Joaquin River Delta. It is a resident of Suisun Marsh. It thrives on alkali flats and other mineral-rich soils. This is a compact subshrub reaching about half a meter tall and wide with erect, multibranched stems. The hairy stems bear small gray-green, nonfleshy, glandular leaves each less than 2 centimeters long. The inflorescences hold clusters of thick, knobby flower heads. Each head is a capsule of layered greenish glandular phyllaries with an array of many cylindrical, protruding golden yellow disc florets at one end.
